In LogCat si vede che:

non so il motivo per cui questo è successo due volte.

Per ulteriori visualizzo il mio Manifest.xml qui: Manifest.xml

Answer 1

I have recr mangiato il tuo erroreIl problema è nella vostra res/xml/contacts.xml file di

Modifica questa linea:

xmlns:app="com.satyamdswt.agreader" 

a questa linea:

xmlns:app="http://schemas.android.com/apk/res/com.satyamdswt.agreader" 

È giusto formato di namespace XML della vostra applicazione: http://schemas.android.com/apk/res/package_name

Upd : Non è necessario modificare altri parametri nel tag <cursor-adapter>. Forma destra:

<cursor-adapter xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res/com.satyamdswt.agreader" 
    app:uri="content://com.android.contacts/contacts" 
    app:selection="has_phone_number=1" 
    app:layout="@layout/contact_item"> 

Answer 2

Put contacts_list.xml nella cartella layout http://developer.android.com/resources/samples/XmlAdapters/res/layout/contacts_list.html

scaricare il file da qui e mettere nella cartella layout http://developer.android.com/resources/samples/XmlAdapters/res/layout/index.html

EDIT

Credo che l'errore è con questo file http://developer.android.com/resources/samples/XmlAdapters/res/xml/contacts.html

Si prega di verificare se si ha il layout "contact_item" nella cartella di layout

Potete trovarlo qui - http://developer.android.com/resources/samples/XmlAdapters/res/layout/contact_item.html
